Figure 3.

SEM showing that quality of sleep causally mediates emotional behavior by regulating the levels of intracortical myelin of anterior OFC (A), but not of middle temporal (B). (C) Same SEM showing no effect of sleep amount on emotional behavior via the regulation mid-posterior cingulate intracortical myelin. Note that each element of the SEM is also influenced by an independent latent error (e_PSQI or e_Sleep amount, e_myelin, e_emotion). See Table 6 for the results of the SEM analyses and associated statistics.
